In a purely resistive AC circuit where 240V is applied across a 10-ohm resistor the amperage is?

Since Ohm's law states that current is voltage divided by resistance, if you place 240 volts across 10 ohms, you will get 24 amperes. This is true for AC and DC. It is also true for inductive or capacitive circuits, except that the calculation of apparent resistance (reactance) and phase angle of current to voltage becomes more complex.


What voltage required to send a current of 4 amps through a resistance of 60ohm?

To find the voltage required to send a current of 4 amps through a resistance of 60 ohms, you can use Ohm's Law: V = I x R where V is the voltage, I is the current, and R is the resistance. Plugging in the values: V = 4 amps x 60 ohms V = 240 volts So, you would need 240 volts to send 4 amps through a 60-ohm resistor.


An electric clothes dryer has a resistance of 16 ohms It draws 15 A of current What is the voltage in volts of the wall outlet that it is plugged into?

We know that Voltage = Current x Resistance, so if E = I x R, then E = 20 x 12 = 240 volts, and the dryer must be plugged into a 240 volt outlet.


Is a 10 ampere fuse suitable for 240 volt?

Yes a 10 amp fuse can be used to protect a 240 volt circuit. The amperage rating of a fuse is based on the given amperage load of the circuit. The voltage rating on a fuse must match or be higher than the voltage that is applied to the fuse. In other words you can not use a 240 volt fuse on a 277, 347, 480 or 600 volt circuit but it can be used on a 120 volt, Manufactures of switching equipment today make it impossible to interchange different voltage fuses to be installed in higher voltage switches.

What is the function of 240 ohms resistor?

To provide 240 ohms of resistance. What those 240 ohms do in an actual circuit depends on the intention of the designer.


What is the resistance of a conductor that carries a current of 120 amperes when the potential difference between its ends is 240 volts?

The resistance of the conductor can be calculated using Ohm's Law: resistance (R) = voltage (V) / current (I). Plugging in the values gives: R = 240 V / 120 A = 2 ohms.


Determine the secondary and primary current for a transformer which has primary voltage 1440V and secondary 240V and turns ratio of 6 if the secondary is loaded with a resistive load of 60 ohms?

An ideal lossless transformer with a primary voltage of 1440 and a secondary voltage of 240 will deliver 4 amperes to a 60 ohm load by ohms law 240 volts divided by 60 ohms causes 4 amperes to flow through the 60 ohm load. The power delivered to the 60 ohm load will be 4 amperes times the 240 volts or 960 watts. The current in the primary is divided by the primary to secondary ratio of 6. Thus, the primary current will be 4 amperes divided by 6 or 2/3 ampere. The power going into the primary will be 1440 volts times 2/3 amperes or 960 watts. In a real transformer there is losses that make the numbers change. The output voltage will be slightly less and the resistance and reactance of the windings lower the output.

What is the difference between 220 amps and 240 amps?

The difference between 220 amps and 240 amps lies in their amperage ratings. 220 amps denotes a current capacity of 220 amperes, while 240 amps indicates a current capacity of 240 amperes. The higher the amperage, the greater the power capacity for electrical devices.


An alarm clock draws 0.5 a of current when connected to a 120 volt circuit calculate its resistance?

Using Ohm's Law (V=IR), we can rearrange the formula to solve for resistance: R = V/I. Plugging in the values, R = 120 volts / 0.5 amps = 240 ohms. Thus, the resistance of the alarm clock is 240 ohms.
