Consider that you have a series circuit containing a 12-volt battery and 50 ohm, 80 ohm, and 100 ohm resistors. what is the total amount of resistance in the circuit?

230 ohm

Explanation:

V = 12 V

R1 = 50 ohm

R2 = 80 ohm

R3 = 100 ohm

This is the circuit containing three resistors which are connected in series and a battery is also connected in the circuit.

The formula for the equivalent resistance when the resistances are connected in series is given by

Where, Rs be the equivalent resistance of the three resistances which are connected in series.

Rs = 50 + 80 + 100

Rs = 230 ohm

Thus, the total amount of the resistance in the circuit is the equivalent resistance which is equal to 230 ohm.

the answer is b, have negligible mass
