Answer to Question #166432 in Electric Circuits for Sara Gulzar

Question

A battery of emf 12v and internal resistance 1.5 ohms connects across a 10 ohm resistor.

Calculate the current of the circuit

Calculate the terminal voltage

Answer 1

Calculate effective resistance,

$R_E=1.5\Omega +10\Omega=11.5\Omega$

$I=\frac{V}{R}=\frac{12}{11.5}=1.0435A$

Terminal voltage$=IR=1.0435\times 1.5=1.5653v$
