The current in a series circuit is 21.2 A. When an additional 7.38-Ω resistor is inserted in series, the current drops to 12.2 A. What is the resistance in the original circuit?

Four resistors, R, = 12 0, R2 = 15 N, R3 = series combination of R, and R2 is connected in parallel with the series combination of R3 and R4. The combination is then connected across a 12 V DC power supply. 10 N and R4 80 are connected such that the %3D %3D A. Draw the schematic diagram and label the circuit elements. B. Calculate the equivalent resistance of the circuit. C. Find the total current of the circuit, the voltage across each resistor and the current through each resistor.

A 30 Ohm resistor and 1.673 F capacitor are connected in series to a 60 V DC voltage source (RC Circuit). What will be the charge stored in the capacitor 4.38 seconds after the series is connected?

Three resistors with resistances R1 = 0.91 ohm, R2 = 6.06 ohm, and R3 = 8.05 ohm are is series circuit with a 14 volt battery. How much current (Ampere) can move through the circuit

You have 2 resistors (R1=220. ohm, R2=100. ohm) that are in parallel with each other.  These 2 are in series with a third resistor (R3=22.0 ohm).  These resistors are in a circuit with a 5.00 V DC power supply (see circuit diagram in Figure 7, pg 47 in your lab manual).  From this information, find Vtot, Req, Itot, I1, I2, I3, V1, V2 and V3.  Show all of your work including units

The capacitor shown below has an initial voltage of 0.15 V before the switch is closed. The resistance is 8.5 x 106 ohms and the capacitance is 2.0 microfarads. How long after the switch is closed in seconds does it take for the voltage across the resistor to drop to 0.083 V? R CH B A D

Circuit Problem: Express each labelled voltage and current (e.g., vx, ix) in terms of the resistances and source currents and voltages (e.g., R0).
