Find the equivalent resistance of the following circuit. If the battery voltage is 4.5V find the electric current of the circuit.
Answers
❏ Solution:-
From the above attachment,
➝The equivalent resistance between the terminal A&C is,
➝The equivalent resistance between the terminal C&D is,
➝The equivalent resistance between the terminal D&E is,
➝The equivalent resistance between the terminal A&G or the equivalent resistance of the whole circuit is ,
Hence, equivalent resistance(R) of the circuit is 7.5 ohms,
Now, Voltage(V) is = 4.5 volt,
Hence, current(I) through the circuit is = 0.6 A.
