Does Increased resistor wattage effect peak amperage output? Answered
Hello, I am in the process of building a 900W+ (60v ~14a) RC EDM generator. I am using a heavily modified hairdryer heating coil at 4 Ohms resistance at about 1200 watts. According to my calculations (derate transformer output wattage 20% in order to obtain minimum wattage required), I needed a minimum of 720 watts of dissipation on the resistor. Would it be okay to use a higher wattage resistor without any amperage drop on the circuit while it is operating?
