Question 6
What is the total circuit resistance of this circuit?
Rtotal = R1 + R2 = 100 + 100 = 200 ohms
Question 7
Find the current through each resistor and the voltage drop across each resistor.
The current through each resistor in series is the same:
I = Vtotal / Rtotal = 240 / (20+10+70) = 2.4 A
The voltage drop across each resistor is the product of their resistance and the current through them:
V1 = 2.4 * 20 = 48 V
V2 = 2.4 * 10 = 24 V
V3 = 2.4 * 70 = 168 V
Question 8
Two resistors are connected to a power supply in series. The power supply produces a 10 V. The current that runs through the circuit is 1.0 A. If one resistor has a resistance of 7 Ω, find the resistance of the other.
The total resistance of the circuit is given by Ohm’s Law:
Rtotal = Vtotal / I = 10 V / 1.0 A = 10 ohms = R1 + R2
R2 = Rtotal - R1 = 10 - 7 = 3 ohms
Question 9
A set of Christmas tree lights consists of 20 globes, each with 10 Ω of resistance, wired in series. Find the voltage drop across three consecutive globes if the lights are connected to a 240 V supply.
The current through the circuit is given by
I = Vsupply / Rtotal = 240 / (20 * 10) = 1.2 A
The voltage drop across three consecutive globes depends on their total resistance:
V 3 globes = I(Rn + Rn+1 + Rn+2) = 1.2 * (3 *10) = 36 V
Question 10
Mark the potential at points A, B, and C.
I = 20 V / 100 ohms = 0.2 A
A = +16 V
B = +14 V
C = +6 V
