7) The circuit shown in the figure consists of two identical bulbs illuminating with equal intensity, and a 12V battery. When the switch is closed, the intensity of the light bulb A brightens: a) Increase b) Decrease c) Does not change d) Turns off A B (000)

Check Your Understanding Circuit breakers in a home are rated in amperes, normally in a range from 10 amps to 30 amps, and are used to protect the residents from harm and their appliances from damage due to large currents. A single 15-amp circuit breaker may be used to protect several outlets in the living room, whereas a single 20-amp circuit breaker may be used to protect the refrigerator in the kitchen. What can you deduce from this about current used by the various appliances?

2. A 0.30-m-long metal bar is moving to the left at constant speed of 20 m/s perpendicular to a uniform 2.0 T magnetic field. The bar rides on parallel metal rails connected through a 6.00 resistor, so the apparatus makes a complete circuit, as shown in the figure below. Ignore the resistance of the bar and the rails.

Q24) An ammeter has a range of (0-22.5mA) has guaranteed accuracy of ±3.125% of half scale and a wattmeter with range (0-183W) with ±6.25% of full-scale guaranteed accuracy are used to measure the power loss in transmission line. Then, calculate i. %limiting error of power for the measurement of 93.45W ii. %limiting error of current for the measurement of 13.67A iii. %limiting error of voltage

Assignment 3.) A power transmission from line is hung metal towers with glass insulators having a resistance of 1.00×10⁹ . What current flows through the insulator if the voltage is 200 kV? (Some high-voltage lines are DC.) Is the value of your answer high or low? Explain why. 99999 iStock by Getty Images

2. What happens to the electrical signal as it reaches the radio receiver? * It generates a low-frequency electrical signals and low voltage It generates a high-frequency electrical signals and high voltage It generates a low-frequency electrical signals but is high in voltage. It generates a high-frequency electrical signals but is low in voltage.

A string of 16 identical holiday tree lights is connected in series to a 120 V source. The string dissipates 64 W. a) What is the equivalent resistance of the light string? b) What is the resistance of a single light? c)What power is dissipated by each light?

5. Decode the nominal, minimum, and maximum value of the resistor whose color codes are: orange, black, brown, gold 6. Decode the nominal, minimum, and maximum value of the resistor whose color codes are: gray, blue, black, black, red 7. Decode the nominal, minimum, and maximum value of the resistor whose color codes are: white, black, black, silver

Q2) Two real batteries of emfs &, = 2 V and Ɛ2 = 6 V and internal resistances r, = 0.40 N and r2 = 0.80 N, a capacitor of capacitance C = 20 µF and a switch S are placed within a circuit, as shown in the figure. What is the difference between the charge on the capacitor when the switch S is open and when it is closed? (10p) (In both cases assume that the switch is open or closed for a long time such that the current is stabilized.)
