Question

D. How much current is passing through each resistor?

e. Calculate the voltage drop across each resistor.



f. How does the voltage drop across each resistor compare to the voltage of the battery?





4. Three resistors with values of 12 Ω, 24 Ω and 6 Ω are connected in series to one another and a 24 V power supply. Draw the circuit and fill in the data table.

5. Three resistors with values of 3 Ω, 5 Ω and 7 Ω are connected in a circuit, as shown. When the switch S1 is in the position shown on the diagram only two resistors, R1 and R2, are connected to the 36 V battery and the current is I1. If the switch is moved to it’s down position the third resistor R3 is connected in series to R1, R2, and the battery, producing a current I2. Find the current reading of the ammeter, I1 and I2, for the two different switch positions.

Answer 1

d. V=12 R=12
I=V/R so Current = 1 amp

e.3 ohm resistor
V=IR
V=3 V

At the 4 ohm
4 V
And at the 5 ohm
5 volts

f. The voltage drops across the resistors add up to give the voltage supplied by the battery
