Collect data: Measure the current in the circuit using the resistor and voltage combinations given below.
Voltage Resistance Current:
10 20
20 20
30 20
To measure the current in the circuit, we can use Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R).
For the first combination:
V = 10V, R = 20 ohms
I = V / R
I = 10 / 20
I = 0.5 A
For the second combination:
V = 20V, R = 20 ohms
I = V / R
I = 20 / 20
I = 1 A
For the third combination:
V = 30V, R = 20 ohms
I = V / R
I = 30 / 20
I = 1.5 A
So, the current through the circuit for the given combinations are:
10V, 20 ohms - 0.5 A
20V, 20 ohms - 1 A
30V, 20 ohms - 1.5 A
