Current:
To calculate the current in the circuit, we can use Ohm's Law, which states:
Current (I) = Voltage (V) / Resistance (R)
For the given combinations:
1) Voltage = 30 volts, Resistance = 20 ohms
Current = 30 volts / 20 ohms = 1.5 amperes
2) Voltage = 30 volts, Resistance = 100 ohms
Current = 30 volts / 100 ohms = 0.3 amperes
3) Voltage = 30 volts, Resistance = 200 ohms
Current = 30 volts / 200 ohms = 0.15 amperes
Therefore, the currents in the circuit for the given resistor and voltage combinations are as follows:
1) 1.5 amperes
2) 0.3 amperes
3) 0.15 amperes
