0. You have two base bias circuits connected for testing. They are identical except that one is biased with a separate VBB source and the other is biased with the base resistor connected to Vcc- Ammeters are connected to measure collector current in each circuit. You vary the Vcc supply voltage and observe that the collector current varies in one circuit, but not in the other. In which circuit does the collector current change? Explain your observation.

Review. A novel method of storing energy has been proposed. A huge underground superconducting coil, 1.00 kin in diameter, would be fabricated. It would carry a maximum current of 50.0 kA through each winding of a 150-turn Nb3Sn solenoid. (a) If the inductance of this huge coil were 50.0 H. what would be the total energy stored? (b) What would be the compressive force per unit length acting between two adjacent windings 0.250 in apart?
A Van de Graaff generator (see Fig. 25.23) is operating so that the potential difference between the high-potential electrode and the charging needles at is 15.0 kV. Calculate the power required to drive the belt against electrical forces at an instant when the effective current delivered to the high-potential electrode is 500 A. Figure 25.23 Schematic diagram of a Van de Graaff generator. Charge is transferred to the metal dome at the top by means of a moving belt.
An AC power supply produces a maximum voltage Vmax = 100 V. This power supply is connected to a resistor H = 24.0 , and the current and resistor voltage are measured with an ideal AC ammeter and voltmeter as shown in Figure P33.3. An ideal ammeter has zero resistance, and an ideal voltmeter has infinite resistance. What is the reading on (a) the ammeter and (b) the voltmeter?
A man foolishly tries to fish a burning piece of bread from a toaster with a metal butter knife and comes into contact with 120-V ac. He does not even feel it since, luckily, he is wearing rubber-soled shoes. What is the minimum resistance of the path tire current follows through the person?
Using information in Example 20.6, what would the Hall voltage be if a 2.00T field is applied across a 10-gauge copper wire (2.588 mm in diameter) carrying a 20.0-A current?
An audio amplifier, represented by the AC I source and resistor in Figure P33.7, delivers to the speaker alternating voltage at audio frequencies. If the source voltage has an amplitude of 15.0 V, R = 8.20 . and the speaker is equivalent to a resistance of 10.4 . what is the time-averaged power transferred to it?
Explain in not more or less than 5 sentences. 1. For each of the following situations, identify which point is at a higher potential,and indicate the direction of the conventional current (whether A B or B to A):a) point A is at +25 V and point B is at +20 V b) point A is at -15 V and B at -8 V 2. Enumerate the condition(s) for a PN junction to:a) block current b) pass current
To get the minimum current, the connection should be in series. If you create a series connection with 30V DC source and three resistors with R1 = 50Ω, R2 = 75Ω, and R3 = 100Ω, how do you calculate for the total current (IT) and the current flowing in each resistor (I1, I2, I3), and the total voltage (VT) and the voltage across each resistor (V1, V2, V3)? How do you also determine the power dissipated by each resistor (P1, P2, P3) and by the whole circuit (PT)??
How can we analyze complex resistors?
Advanced Math A bipolar alkaline water electrolyzer stack module comprises 160 electrolytic cells that have an effective cell area of 2 m2. At nominal operation, the current density for a single cell of the electrolyzer stack is 0.40 A/cm2. The nominal operating temperature of the water electrolyzer stack is 70 oC and pressure 1 bar. The voltage over a single electrolytic cell is 1.96 V at nominal load and 1.78 V at 50% of nominal load. The Faraday efficiency of the water electrolyzer stack is 95% at nominal current density, but at 50% of nominal load, the Faraday efficiency decreases to 80%.
