Question
1.5 Ω, 0.5 Ω and 2.5 Ω resistors are connected in series. Find the total resistance of these 3 resistors if a 6 V battery is connected to the circuit?
Solution
The total resistance (R_total) of resistors connected in series is simply the sum of all the individual resistances.
So, in this case, you just need to add up the resistances of the 1.5 Ω, 0.5 Ω and 2.5 Ω resistors.
R_total = R1 + R2 + R3 R_total = 1.5 Ω + 0.5 Ω + 2.5 Ω R_total = 4.5 Ω
So, the total resistance of the circuit is 4.5 Ω. The voltage of the battery doesn't affect the total resistance of the circuit, so we don't need to use it in this calculation.
