You have a circuit consisting of a power supply,
switch, resistor, two capacitors, and
voltage/current probes. The resistor has the
value R1 = (1.8 ± 10%) MQ. The capacitors have
%3D
the values C1 = (0.6 ± 20%) µF and C2 = (2.2 ±
20%) µF. The logger pro data resembles the plot

Label the title and all the axes on the
plot above. Identify which region corresponds
to the capacitors charging and discharging. Be
sure to include appropriate units (MKS).
When switch S in Fig. E25.33 is open, the voltmeter V of the battery reads 3.08 V. When the switch is closed, the voltmeter reading drops to 2.97 V, and the ammeter A reads 1.65 A. Find the emf, the internal resistance of the battery, and the circuit resistance R. Assume that the two meters are ideal, so they don’t affect the circuit.

The capacitors have a value of C1 = 40.0 µF and C2 = 25.0 u F. While finding the actual voltage is very helpful, it's hard to use this as a prediction because not all batteries are the same. So one way to look at this is a percentage. Even if the voltage of the battery is different, the percentage of the voltage should be the same regardless. Find the percentage of the battery voltage that is across capacitor 1.

The half-life is the time required for the quantity to decay to half of its initial value. The time constant for the voltage on a capacitance discharging through a resistance is τ=RC. Find an expression for the half-life of the voltage in terms of R and C.arrow_forwardEngineering students at the University of Houston can take classes where they learn about the theory of electrical circuits. One topic they encounter in these courses is called “Ohm’s law,” and it describes the relationship between the voltage V across a resistor, the electrical current I passing through the resistor, and a quantity R known as the resistance. The law can be written as follows:V = I * R.Voltage is typically measured in volts, while current is measured in amperes (amps), and resistance is measured in ohms where 1 ohm equals 1 volt/amp. Lastly, in circuits with variable resistance, the quantities V, I, and R can depend on time.(a) Differentiate Ohm’s Law to find an equation relating the quantities V, I, R, dV/dt , dI/dt , and dR/dt .(b) Suppose that in an electrical circuit the current is increasing at a rate of 0.5 amps per second and the resistance is decreasing at a rate of 4 ohms per second.
