5. A RC-circuit is composed of a resistor and capacitor linked to a battery. Derive the expression for the charging and discharging of a capacitor. Then, determine their respective currents for both charging and discharging. Plot the differences for cach scenario. What are the long term and short term behaviors?

A cook plugs a 400 W crockpot and a 1000 W kettle into a 240 V power supply, all operating on directc When we compare the two, we find that Select one: a. I crockpot > I kettle and Rcrockpot = R kettle. b. I Crockpot = I Kettle and R Crockpot = R %3D %3D Kettle. c. I crockpot R kettle. d. I Crockpot > I Kettle and R Crockpot < R kettle.

As the capacitor in an RC circuit charged, what is the current as a function of time?Explain physically.

a. A heater consists of a variable resistor connected across an ideal voltage supply (no internal resistance). To increase the heat output, should you decrease the resistance or increase the resistance? Explain your answer.

Capacitor A Capacitor B They discharge at the Cannot be same rate determined ww

2. An uncharged capacitor is connected to a battery of potential 10 V through a resistor of resistance 10 kn. If the capacitance of the capacitor is 7µF, how long will it take to charge the capacitor to a charge of 50 µC? What is the time constant of the RC circuit?

A combination of three resistors R1 , R2 and R3 in series is connected across a voltage source VT. The voltage drop across R2 and R3 are 13 V and 29 V, respectively. If the current supplied by the source voltage is 1.5 A and the total power supplied by the source is 90 W, Calculate the following: A. The value of VT and the voltage drop across R1. B.
