Question

20. Two resistances, one 62 and the other 88

are connected in parallel. The resistors are then
connected to a 12-V battery.
a. What is the equivalent resistance of the
parallel combination?
b. What is the current through each resistor?

Answer 1

I'm assuming no internal resistance.

The formula for resistance in parallel combination is 1/total resistance=1/Resistor1/+ resistor/2......

1/Resistance total= 1/88+1/62

1/Resistance total= 75/2728

2728/75

Effective Resistance total= 36.373...ohms

Formula Volts=Current x resistance
V=IR

12=I(36.373.....)

I=0.33A
A=amps
