An electric appliance draws 1.5 amperes of current when it is connected to a 24-volt source - What is the resistance of this appliance?
RawBananas
The formula is Resistance= Voltage/ Amps(current) In your example: R=50/2.5, so the answer is 20 ohms.

If you multiply electric current times resistance what will it be in units?
That depends on what units you use as input. If you put in current in Amps and Resistance in Ohms you will get voltage in Volts.AnswerCurrent is measured in amperes. Resistance is measured in ohms, which is a special name given to a volt per ampere. Multiply amperes by (volts per ohm), and you are left with volts.
What is the relation between the amount of electric current passed and the heat produced?
The relation is:P = I2RWhere:I is the current (for example, in amperes)R is the resistance (for example, in ohms)P is the power (energy per second) converted from electrical energy to heat. If the current is in amperes and the resistance in ohms, then power is in watts (equal to joules/second).
What is the meaning of Ohms?
Resistance is the measure of the degree to which an object will oppose an electric current. The SI unit for resistance is Ohm (Ω). Resistance can be found using the formula R=V/I where R=resistance (Ohms) V=the potential difference across the object (Volts) I=the current through the object (Amperes)
Is The units of electric current is the volt?
NO! (the units of electric current is Amperes).
How much current and circuit that includes a 9- volt battery and a bulb with a resistance of 3 ohms?
A resistance of 3 ohms connected between the terminals of a 9-volt battery will result in a current of 3 Amperes. If the battery is one of those little ones with snaps on top, it may be able to produce 3 amperes of current for about 3 seconds before it rolls over and totally dies.
What is electric pressure called A volts B Amperes C resistance?
Volts.
What is the resistance in a discman if it is connected to an 8.6V battery and draws a current of 0.9 Amperes?
I have no idea
Rate of flow of electric charge is measured in?
Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is related to voltage and resistance by Ohm's law. The standard abbreviations for the units are 1 A = 1C/s.
What must an ammeter be connected to?
To a very small resistance so a mv can be measured as a function of amperes.
What resistance in ohms will allow 20 amperes of current to flow in an appliance if the voltage is 220 volts?
The formula you are looking for is R = E/I
What is the current in a copper wire that has a resistance of 3 ohms and is connected to a 9-volt electrical source?
3 amperes. Ohm's law: Voltage is ohms times amperes.
What is the relationship between electric currentvoltage and resistance?
The relationship is given by Ohm's Law:V = IR (voltage = current x resistance) In SI units: Volts = amperes x ohms
What is the voltage of a small electric heater if the heater is drawing 12 amperes and has a resistance of 10 ohms?
Voltage is current times resistance, 1.2 x 110 = 132 volts.
If you multiply electric current times resistance what will it be in units?

What is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
What is the resistance of an electric frying pan that draws 12 amperes of current when connected to a 120 volt circuit?
Given R=? I=12 ampere V=120 Volts equation I=V divided R Solution; R=12 ampere 120 Volts answer (10)
What is the resistance of a 120-W incandescent lamp connected to a 120-V power supply?
Power (watts) = current (amperes) * voltage (volts) Current (amperes) = voltage (volts)/resistance (ohms) 120 watts = current * 120 volts current = 1 ampere 1 ampere = 120 volts/resistance resistance = 120 ohms
