What some people write as 0.2 Amps is the same as 200 milliAmps or 2x1/10Amp.
Not enough information to answer.
To employ Ohms law to calculate this you need the resistance of the circuit.
Electrical current is measured in amperes.
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
Ohm's Law: Voltage is resistance time current So, 28 ohms and 3.8 amperes means 106.4 volts.
Electrical power = current x voltage Current is in amps
Six amperes. Use Ohm's law: the current is the voltage divided by the resistance
Electrical current is measured in amperes.
EMF is electromotive force. It is another name for voltage. Voltage is electric potential in joules per coulomb. Current is electric flow, in amperes. Amperes are coulombs per second. Voltage and current are not the same thing, and "emf current", or "voltage current" does not make sense.
That depends on the voltage which the current flows through. I = P / U I = 1500 / U Where I is the current in Amperes and U is the effective voltage in Volts. (P is the power)
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
"Magnitude" means how strong it is - how much voltage (how many volts), or how much current (how many amperes).
Amperes and volts, respectively.
Ohm's Law: Voltage is resistance time current So, 28 ohms and 3.8 amperes means 106.4 volts.
Electrical power = current x voltage Current is in amps
Voltage is power Amperage is current. you can have voltage but nothing runs without a closed circuit and then current flows.
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
Voltage is the "pressure" that pushes electrons thru a circuit, higher voltage means more current, or amperes. Amperes and the number of turns of wire in the magnet control the force of the magnet
