Question

3) Given R, = 4 ohms and R, = 5 ohm and V = 18 volts

d) Find the total resistance: I
Find the current in the circuit:
f) Find the voltage drop in each resistor:

Answer 1

d) the total resistance is 4 + 5 = 9 ( ohm)

e) the current in the circuit is 18/9 = 2(A)

f) the voltage in R = 4 ohm is 2.4 = 8 (V)

the voltage in R = 5 ohm is 18 - 8 = 10 (V)
