Question

Determine the current going through the 5 resistor in the following circuit.

• A. $0.5A$
• B. $1.0A$
• C. $2.0A$
• D. $50A$

Answer 1

Answer: (A)

$0.5A$

Equivalent resistance of the circuit $R_{eq}=5+15=20$ $\Omega$

Voltage of the battery $V=10$ volts

Thus current going through $5\Omega$ $I=\frac{V}{R_{eq}}=\frac{10}{20}=0.5$ $A$
