What resistance must be added in series to a circuit containing a 33 ohms resistor in order to draw 2.0 Amps of current from a 120 volts source?
Asked by bcnandi | 12 May, 2019, 16:09: PM
answered-by-expert Expert Answer
Resistance = voltage / current = 120/2= 60Ω
 
since the circuit already has 33 Ω resistance, additional series resitance required = 60-33 = 27Ω
