resistor Quiz Practice Quiz | Resistor

To oppose the flow of current. — Resistors impede current flow, controlling the current in a circuit.

Ohm (?) — Resistance is measured in Ohms, named after Georg Ohm.

It opposes current flow more. — Higher resistance means greater opposition to the flow of electrons.

1 kOhm ± 5% — Brown=1, Black=0, Red=x100, Gold=5% tolerance. 10 x 100 = 1000 Ohms (1 kOhm).

Carbon composition and wirewound — Carbon composition and wirewound are common types of resistors.
