what is the current prouce by a potential difference of 240 volts through a resistance of 0.2 ohms?
V = i R
240 = i (.2)
i = 240/.2 = 2400/2 = 1200 amps (welding current, big sparks)
To calculate the power (P) produced by a potential difference (V) through a resistance (R), you can use the equation: P = V^2 / R.
Using this equation, let's calculate the power:
P = (240 volts)^2 / 0.2 ohms
P = 57,600 volts^2 / 0.2 ohms
P = 288,000 watts
Therefore, the current produced by a potential difference of 240 volts through a resistance of 0.2 ohms is 288,000 watts.
To determine the current produced by a potential difference (voltage) through a resistance, you can use Ohm's Law. Ohm's Law states that the current (I) flowing through a circuit is equal to the potential difference (V) across the circuit divided by the resistance (R) in the circuit.
Mathematically, Ohm's Law can be expressed as:
I = V / R
In this case, the potential difference (V) is given as 240 volts, and the resistance (R) is given as 0.2 ohms. Plugging these values into the formula, we can calculate the current (I):
I = 240 / 0.2
I = 1200 amperes
Therefore, the current produced by a potential difference of 240 volts through a resistance of 0.2 ohms is 1200 amperes.
