Current through 5 omg resistor is?
Answers
Given :
Three resistances are connected as shown in the figure.
Voltage of battery = 12V
To Find :
Current through 5Ω resistor.
Solution :
❒ First of all we need to find equivalent resistance of the circuit
A] 10Ω and 6Ω are connected in parallel, their equivalent resistance will be
➙ 1/r = 1/10 + 1/6
➙ 1/r = (3+5)/30
➙ r = 30/8
➙ r = 3.75 Ω
B] Finally 3.75Ω and 5Ω come in series, so final equivalent resistance will be
➙ R = r + 5
➙ R = 3.75 + 5
➙ R = 8.75Ω
As per ohm's law, current flow in conductor is directly proportional to the applied potential difference. [V = IR]
❖ Net current flow in the circuit :
➛ V = I × R
➛ 12 = I × 8.75
➛ I = 12/8.75
➛ I = 1.37 A
We know that current flow in each resistors is same in series connection.
Therefore current through 5Ω resistor = 1.37A
Answer:
Question :-
❖ the current through the 6Ω resistor...
Solution :-
➛ V = I × R
➛ 12 = I × 8.75
➛ I = 12/8.75
➛ I = 1.37 A
