Collect data: Measure the current in the circuit using the resistor and voltage combinations given below.
Voltage
10 volts
20 volts
30 volts
Resistance
20 ohms
20 ohms
30 ohms
Current:
To calculate the current in the circuit, we can use Ohm's Law:
Current (I) = Voltage (V) / Resistance (R)
For the first combination (10 volts, 20 ohms):
I = 10 / 20 = 0.5 amps
For the second combination (20 volts, 20 ohms):
I = 20 / 20 = 1 amp
For the third combination (30 volts, 30 ohms):
I = 30 / 30 = 1 amp
So, the current in the circuit for the given combinations is:
- 10 volts with 20 ohms resistor: 0.5 amps
- 20 volts with 20 ohms resistor: 1 amp
- 30 volts with 30 ohms resistor: 1 amp
