Answer 2

Answer 3

ANSWER :

1. True

2. False

3. False.

4. True

5. 

I1 = Current through R1 = V/R1 12/3 = 4 amps ( ANSWER)

6.

I3 = Current through R3 and R4 = V/((r3 + R4) = 12/(2 + 4) = 2 amps.

So,

V3 = Voltage across R3 = I3 R3 = 2 * 2 = 4 Volts (ANSWER).

V4 = Voltage across R4 = I3 R4 = 2 * 4 = 8 Volts (ANSWER).

6.

I2 = current through R2 = 12/6 = 2 amps

I = Total current from the battery = I1 + I2 + I3 = 4 + 2 + 2 8 amps

Total resistance of the system, R = V/I = 12/8 = 1.5 Ω (ANSWER).
