480 volts and 60ohm impedence
current = volt/impedence
current=480/60
current=8ampeares
A circuit has an applied voltage of 100 volts and a resistance of 1000 ohms. The current flow in the circuit is 100v/1000ohms which would equal .1.
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
Ohms Law says that Voltage = Current * Ohms, so the twothings that can affect the voltage in a circuit are Current and Ohms. If have a non resistive impedance, i.e. a capacitor or inductor forming a reactance, then frequency can also affect the voltage but, mathematicaly, reactance is a frequency domain form of impedance, so my answer stands - Current and Ohms.
In a 12VDC circuit with a 1K load, there will be 12ma of current. (Ohm's law: Volts = Amps * Ohms, so Amps = Volts / Ohms.)
The resistance of the circuit will be 46 ohms

resistance to the flow of electrical current in the circuit. It is a measure of how much opposition the circuit presents to the flow of electricity. The higher the number of ohms, the greater the resistance in the circuit.
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
24 Ohms
Ohms do not relate to power per se. Ohms do however contribute how much power a circuit can deliver. In a given circuit the lower the resistance (measured in ohms) the higher the current & higher the power. This is assuming the voltage remains constant.
Ohms Law says that Voltage = Current * Ohms, so the twothings that can affect the voltage in a circuit are Current and Ohms. If have a non resistive impedance, i.e. a capacitor or inductor forming a reactance, then frequency can also affect the voltage but, mathematicaly, reactance is a frequency domain form of impedance, so my answer stands - Current and Ohms.
Ohms law states E=I*R. Isolating I we get, I = E/R.I = 60V/12ohms = 5 amps.
In a 12VDC circuit with a 1K load, there will be 12ma of current. (Ohm's law: Volts = Amps * Ohms, so Amps = Volts / Ohms.)
The resistance of the circuit will be 46 ohms
Just use Ohms Law: V=IR, that is, voltage (in Volt) = current (in Ampere) x resistance (in Ohms).
ohms is a measure of resistance(R) in a circuit. Watts is a measure of the power(P), in this case lets assume it is the power used by the resistive element (lamp, heater etc). Power(watts)=Current(Amps)x Current(amps) x Resistance(ohms) or Resistance (ohms)=Power(W)/(current x current)
