Calculate the EMF of a current source of resistance 0.2 Ohm, when connected to which a resistor with a resistance of 0.4 Ohm, a circuit current of 1.5A is created.
Initial data: r (resistance of the current source) = 0.2 Ohm; R (resistance of the resistor connected to the current source) = 0.4 Ohm; I (the current that was created in the circuit) = 1.5 A.
You can calculate the EMF of a current source using the formula: Еis = I * (r + R).
Calculation: Еis = 1.5 * (0.2 + 0.4) = 0.9 V.
Answer: The EMF of the current source is 0.9 V.
