DC Series Circuit Revision

A series circuit is one in which resistances are connected so that there is .......... path for the current to flow through it.

• One

• Two

• Three

• Four

The formula for the total resistance (RT) is:

• RT = R1 + R2 + R3

• RT = R1 - R2 - R3

• RT = R1 x R2 x R3

• RT = R1 = R2 = R3

The formula for the total current (IT) is:

• IT = I1 + I2 + I3

• IT = I1 - I2 - I3

• IT = I1 x I2 x I3

• IT = I1 = I2 = I3

The formula for the total voltage (VT) is:

• VT = V1 + V2 + V3

• VT = V1 - V2 - V3

• VT = V1 x V2 x V3

• VT = V1 = V2 = V3

The total resistance in a series circuit is smaller than the smallest resistance in the circuit.

• True

• False

If a lamp is broken or disconnected in a series circuit, the other lamps will keep working.

• True

• False
