How many amperes of current will flow in a circuit if the voltage difference is 9 V and the resistance in the circuit is 3 Ω?
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
What happens to the current if the voltage is reduced by a factor of 3 and the resistance is constant?
Ohm's Law: V = I*R, so Voltage and Current are directly proportional and a change in voltage will result in a proportional change in current. (The current reduces by the same factor)
What voltage is necessary to produce a current of 200 amperes through a resistance of 1 X 10-3 ohms?
voltage = current x resistance, so: voltage = 200 x 0.001 = 0.2 volts
What current will be needed to produce a voltage of 5V across a 12kΩ resistor?
Ohm's Law: Current = voltage divided by resistance. 5 V divided by 12 KΩ is 416 2/3 ma
What are the 3 basic features all electric circuits must have?
3 components ; voltage supply or battery connection wires or wiring a lamp bulb to indicate presence of current flow within the circuit when current is actually flowing within the wires.
According to Ohm's Law how is voltage related to resistance and current?
1). Voltage = (resistance) x (current)2). Current = (voltage) / (resistance)3). Resistance = (voltage) / (current)I think #2 is Ohm's original statement, but any one of these can be massaged algebraicallyin order to derive the other two.
What are the 3 elements of electricity?
voltage current resistance
What is the resistance in a simple circuit if voltage is 12 volts and current is 3 amps?
Ohm's Law: Resistance = voltage / current, so 12 / 3 = 4 ohms.
How much current flows through a 12 ohm flashlight bulb operating at 3.0 volts?
Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.Ohm's Law: Voltage = current x resistance; solving for voltage, current = voltage / resistance.
What are the 3 basic elements of electricity?

What are 3 basic electrical quantities?
Voltage current resistance
How many amperes of current will flow in a circuit if the voltage difference is 9 V and the resistance in the circuit is 3 Ω?
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
In 3 phase voltage increases and current decreases why?
If the load current descrease, there is less voltage drop caused by the resistance of the wire, so the voltage is higher.
How do you calculate the resistance in a circuit in which a 9-volt battery produces 3 amperes?
Where V=stands for voltage, I=stands for current and R=stands for resistance. voltage=current multiplied by resistance so, by transposition, resistance=voltage divided by current. or R=V/I, R=9/3 The resistance is 3 ohms.as by ohm's law, v=irr = v/itherefore the resistance is 9/3=3 ohms
What voltage is needed to produce 6 A current through a resistance of 3?
18volts
What is the voltage of an appliance that has a current of 3 amps and a resistance of 4 ohms?
12 volts.
What happens to the current if the voltage is reduced by a factor of 3 and the resistance is constant?
Ohm's Law: V = I*R, so Voltage and Current are directly proportional and a change in voltage will result in a proportional change in current. (The current reduces by the same factor)
