Answer to Question #265347 in Electricity and Magnetism for Fero

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:

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