closed

The cutest little circuit evah!

The picture shows an electrical circuit. This circuit is a series circuit because:

It has 3 light bulbs.

The same current flows through all three light bulbs.

It uses a single battery.

The electrical current has more than one path to flow through

A correct statement of Ohm’s Law is:

I= V R

V ∝ I

V = IR

both b and c
