A device consume 100w of power when connected to a 100 v source.
Calculate its resistance
To calculate the resistance, we can use Ohm's Law, which states that resistance (R) is equal to the ratio of voltage (V) to current (I):
R = V/I
We know that the power (P) is equal to the product of voltage and current:
P = V * I
In this case, the power is given as 100 watts, and the voltage is given as 100 volts. We can rearrange the equation for power to solve for current:
I = P/V
Substituting the given values, we find:
I = 100 watts / 100 volts = 1 ampere
Finally, we can use Ohm's Law to calculate the resistance:
R = V/I = 100 volts / 1 ampere = 100 ohms
Therefore, the resistance of the device is 100 ohms.
To calculate the resistance of the device, we can use Ohm's Law, which states that the resistance (R) is equal to the voltage (V) divided by the current (I). In this question, we are given the power (P) and the voltage (V) of the device.
We know that power (P) is equal to the voltage (V) multiplied by the current (I). In equation form, this is represented as P = V * I.
Given:
Power (P) = 100 W
Voltage (V) = 100 V
We can rearrange the equation to solve for current (I):
I = P / V
Substituting the given values into the equation:
I = 100 W / 100 V = 1 A
Now that we have the current (I), we can calculate the resistance (R):
R = V / I = 100 V / 1 A = 100 Ω
Therefore, the resistance of the device is 100 Ω.
