14 ohm X 20 A = 240 V (V=IR)
the answer is 280 14x20 is 280!

How do you work out the current in a circuit?
we can calculate the current in a commmon electrical circuit by this formulae i.e,I=V\R where i is the current flowing in the conductor, R is resistance , V is the voltage.. THE FORMULA IS CORRECT but the term conductor does not suffice an explanation since a conductor is low in resistance R= resistance not conduction.
What does a ammeter measure and what units does it use?
It measures current flow in amps or milliamps. It needs to be in series with the current flow or in the case of a clamp-on meter it must encircle the single conductor carrying current.
Multimeter measure current in amps volts or watts?
A multimeter measures current in amperes and potential difference in volts. Wattmeters are used to measure watts and the reading is a combination of current being drawn and the voltage applied. watt = volts x amps
How do you calculate a starting current?
The formula for the electric current can be given as I= Qt where Q refers to coulomb charge and t= amount of time in second . By applying this formula the amount of current passing through the conductor can be known foor any instant of time. For any conductor the amount of charge is always constant. Current measures the flow of moving charge per unit time. Therefore the formula for current is I=Q/t as the unit of current is C/s (Coulomb's per sec) or amps (A).
How do you figure out an appliance's power consumption if you have the voltage and Frequency and Current?
You just need the voltage and the current. Watts = Amps x Volts.
What is the relationship between voltage and MA?
The "current" through any conductor is voltage across the conductor/conductor's resistance .The current is measured in "Amperes" (amps)."MA" stands for "Milliamps". There are 1,000 of those in one whole ampere.So, the current through a conductor is1,000 times the voltage across the conductor/conductor's resistance . . . in MA

What is the force that causes electrons to move in a conductor?
A charge is transferred (coulombs) and this amounts to an electric current (amps)
How many watts in 10 amps?
Watts and amps measure different things, and they cannot be converted as asked. Watts measures power. Volts measures voltage and amps is a measure of current. The three electrical parameters are related by this formula: Power (watts) = volts times amps. If you know the voltage, then you can find the watt-to-amp ratio.
How much current flows in a 12-watt radio connected to a 120-volt circuit?
Since power = current x voltage, you would divide the power (watts) by the voltage. The answer would be 1/10 amps or .10 amps.
Multimeter measure current in amps volts or watts?
A multimeter measures current in amperes and potential difference in volts. Wattmeters are used to measure watts and the reading is a combination of current being drawn and the voltage applied. watt = volts x amps
What measures amps of current?
An electrical ammeter.
What unit measures tube current?
Measure the plate resistors' (R) voltage (E) and use Ohms law to convert that to amps (I). I=E/R
What is the difference in an ammeter and a multimeter?
An ammeter just measures current (amps), while a multimeter is a single unit that can be switched over to measure other things such as voltage and resistance in addition to current.
What do you put into a circuit to measure current?
An Ammeter. It measures the current (or Amps).
If voltage is not equal to current then are insulators rated in voltage or current?
Insulators are always rated for voltage. Voltage, or potential difference, is the energy that is available to make the electrons jump from the conductor, through the insulator, to the next available conductor. Current is the electron flow through the wire.A great example of why current is not an issue in insulation issues is that you could have 1000 amps (the measurement of current) going through a wire at 1 volt and have no problem with almost any insulator. You would need a very good insulator for less then a amp of current though if the voltage was 100,000 volts.
