Question

Calculate the equivalent resistance for the circuit which is connected to 24V battery and also find the potential difference across 4ohms and 6ohms resistors in the circuit.

Answer 1

For resistors connected in series, the equivalent resistance is

$$R_{eq}=4+6=10\Omega.$$

The current:

$$I=V/R_{eq}=2.4\text{ A}.$$

The voltage drops across the resistors:

$$V_4=IR_4=9.6\text{ V},\\ V_6=IR_6=14.4\text{ V}.$$
