Ohm's Law
Investigate the effect of changing resistance on current.
Part of the course: Electricity & Circuits I — DC Fundamentals
Mission
Investigate the effect of changing the value of the resistance on the value of the electric current in the circuit.
Variables
What you change
- Resistance value
What you measure
- Current
What you keep constant
- Wire length
- Wire cross section
- Battery voltage value
- Temperature of wire
Equations
I = Electric current (A)
R = Electric resistance (ohm)
V = Voltage drop on resistor (V)
I = \frac{V}{R}
