Hello people !
I'm doing an homework in maths and there's some questions that are in relations with what we learn in the electro class. But some of the questions I need to work on were not covered in my electric class so far (we had a day canceled).
I am not asking for straight answers but I'm gonna write the 3 questions that bother me anyway, so I'll be able to ask my questions. (We are in DC).
1. A power (P) of 320mW is dissipated in a resistor (R) of 200 ohms. What is the potencial (in volts) at the terminals of the resistor ?
2. What energy is needed to move a charge of 4,0 mC under a potencial of 60,0V ? (Significant numbers)
3. With the significant numbers:
a) what is the potencial of a resistor knowing that its ohmic value is 15,0 Ω and the current in the circuit is 0,40 A.
b) determine the enegy dissipated in the resistor in one minute.
