If [tex]R_1 = 5 \, \text{ohm}[/tex], [tex]R_2 = 8 \, \text{ohm}[/tex], and [tex]R_3 = 12 \, \text{ohm}[/tex], and a 6 V battery is connected to the series arrangement, calculate:

(a) The total resistance in the circuit.

Answer :

To calculate the total resistance in the circuit we would have 25 ohm.

What is the calculation?

To calculate the total resistance in a series circuit arrangement, we have to add up the individual values. So, the total resistance of the circuit would amount to

Rtotal = R1 + R2 + R3

Rtotal = 5ohm + 8ohm + 12ohm

Rtotal = 25ohm

So, the calculation is a simple one because we only have to add up the values of the three resistance values. The summation of the values in this case gives us 25 ohms.
