an electric drill rated at 400 W is connected to a 240 v. how much current does it draw?
explain your answer
P = V * I = 400W,
240 * I = 400,
1 = 400 / 240 = 1.67 Amps.
an electric drill rated 500w is connected to a 200v power line. How much current does it draw
Well, an electric drill rated at 400 W and connected to a 240 V source would draw a current of about 1.67 Amperes.
But let me break it down for you in a more entertaining way: Imagine the electric drill as a thirsty little monster named Drilly. Drilly has an insatiable thirst for power, and he needs 400 watts of it to satisfy himself.
Now, Drilly is connected to a 240 V power source, which is like a giant energy reservoir. In order for Drilly to get his fill of 400 watts, he needs to suck up a certain amount of current from the source.
So, how much current does Drilly draw? Well, we can use Ohm's Law to figure it out. Ohm's Law states that current is equal to power divided by voltage.
In this case, the power is 400 watts and the voltage is 240 volts. So, when we do the math, we get:
Current = Power / Voltage = 400 W / 240 V = 1.67 A
So, Drilly the electric drill draws approximately 1.67 Amperes of current to fulfill his power-hungry needs. Just make sure to keep him away from water, you wouldn't want him to get even thirstier!
To calculate the current (I) drawn by the electric drill, we can use Ohm's Law, which states that current is equal to voltage divided by resistance.
In this case, we know the power rating (P) of the drill is 400 Watts and the voltage (V) is 240 volts. Ohm's Law can be rewritten as P = VI, where V is voltage and I is current.
Rearranging the formula to solve for current, we have I = P/V.
Plugging in the values, we get:
I = 400 W / 240 V
Calculating this, we find that the drill draws approximately 1.67 Amps of current.
To determine the amount of current the electric drill draws, you can use Ohm's Law. Ohm's Law states that the current (I) flowing through a circuit is equal to the voltage (V) divided by the resistance (R) of the circuit. In this case, the resistance of the circuit is not given, but we can use another formula to find it.
The formula for electrical power (P) is given by P = VI, where P is the power in Watts, V is the voltage in Volts, and I is the current in Amperes. Rearranging the formula, we can determine the current as I = P/V.
Given that the power rating of the electric drill is 400 W and the voltage is 240 V, we can substitute these values into the formula:
I = 400 W / 240 V
Now, let's calculate the current:
I = 1.67 A (rounded to two decimal places)
Therefore, the electric drill draws approximately 1.67 Amperes of current.
