With a voltage across the 220V resistor, the current is 3A, what voltage should be applied to the resistor so that the current is 6A?
Data: U0 (initial voltage) = 220 V; I0 (initial current strength in the taken resistor) = 3 A; I1 (required amperage) = 6 A.
To calculate the voltage applied to the taken resistor with a current of 6 A, we use the equality: U1 / I1 = R (resistance of the taken resistor) = U0 / I0 and U1 = I1 * U0 / I0.
Calculation: U1 = 6 * 220/3 = 440 V.
Answer: To obtain a current of 6A, a voltage of 440V should be applied to the taken resistor.
