Can you explain in detail the question in the photo
1. In a circuit that contains only resistors in series, the current is the same throughout the circuit (remember that current is conserved!). The amount of current in the circuit is determined by the potential difference (or em f) of the battery and the equivalent resistance, Req, of the circuit. We can therefore write Ohm's Law as DeltaV = IReq. Assume the batteries supply a potential difference of DeltaV = 3.0 V, and use the currents measured in circuits 3a, 3b, and 3c to determine the equivalent resistance in each circuit. Please show the calculation of each. R1 = 150 ohm, R2 = 230 ohm R3 = 270 ohms (don't believe question should need these but providing anyways) Current MeasuredCurrent through R1 in 3a (Only resistor 1) Ir1= 0.01 amp Current through R1 in 3b (Resistor 1 and 2) Ir1= 0.0032 amp Current through R1 in 3c (Resistor 1, 2 and 3) Ir1 = 0.002 amp

For the circuit shown in Figure 3: A +1 V1 9V S1 B R1 1kQ2 C1 470μF The circuit in Figure 3 shows the circuit set up to charge and discharge a capacitor. a) Calculate the time constant (T) for the circuit. b) Draw the detailed current waveform through the circuit and voltage waveform across capacitor for the Capacitor charge cycle when the switch is at position A. (Consider the initial capacitor voltage to be OV). c) Draw the detailed current waveform through the circuit and voltage waveform across capacitor for the Capacitor discharge cycle when the switch position is changed to position B. (Consider the capacitor to be fully charged just before the switch position is changed). The waveforms should be labelled, showing the capacitor voltage, currents and time constant. The figures should show as much details as possible, including the time constant and voltage levels. Also write a brief description, explaining the behaviour of the capacitor under the two mentioned cycles.

A series circuit contains a resistance, R, a capacitor, C, supplied by a d.c. source with e.m.f E volt. i) Draw the circuit diagram showing all the elements and variables. ii) Derive an expression for the current in the circuit.

Hints: capacitor charge q = C.v, capacitor current i= q', we have two possibilities for the solution: - Either write the D.E. using capacitor voltage, ve, as the dependent variable then find expression for the current. - Or write the D.E. using capacitor charge as the dependent variable then find expression for the current.

a) The circuit below has three resistors with values R₁-10 S2, R₂-20 S2, R3-30 S2, one initially (t=0) uncharged 0.001 F capacitor, and a 30 V battery. Find all the currents at t=0 (right after the switch is closed,) all the currents a long time after the switch is closed (at steady state), and the charge on the capacitor at t→∞. At time ti, once steady state with the switch close has been effectively reached, the switch is reopened. Find the currents at this time, right after reopening the switch. Make sure to make your reasoning clear! R₁ - 18 S www R₂ www.
