Given that the power consumed by a device is 1000 W operating on a 70-V line, calculate the amount of current it draws.
P=I•U
I = P/U = 1000/70 =14.29 A
thanks so much
How many extra electrons are on this particular oil drop (given the presently known charge of the electron)?
never mind wrong question
To calculate the amount of current drawn by a device, you can use Ohm's Law, which states that the current (I) flowing through a device is equal to the power (P) consumed by the device divided by the voltage (V) across the device.
The formula is:
I = P / V
Where:
I = Current
P = Power
V = Voltage
In this case, we are given the power (P) as 1000 W and the voltage (V) as 70 V.
Plugging these values into the formula:
I = 1000 W / 70 V
Calculating this, we get:
I = 14.29 A
Therefore, the device draws approximately 14.29 Amperes of current.
