What is a simple circuit?
A simple circuit is one in which there is a single voltage source and a single resistance. One statement of Ohm’s law gives the relationship between current I, voltage V, and resistance R in a simple circuit to be I=VR I = V R . Resistance has units of ohms (Ω), related to volts and amperes by 1 Ω = 1 V/A.

What 3 things do you need for a circuit?
Every circuit is comprised of three major components:
- a conductive “path,” such as wire, or printed etches on a circuit board;
- a “source” of electrical power, such as a battery or household wall outlet, and,
- a “load” that needs electrical power to operate, such as a lamp.
What happens in a simple circuit?
In the scientific model for this kind of simple circuit, the moving charged particles, which are already present in the wires and in the light bulb filament, are electrons. … When it is connected to a complete circuit, electrons move and energy is transferred from the battery to the components of the circuit.
