Class XII If a series?parallel circuit has all 30-ohm resistors, what is the total resistance when R1 is in series with a parallel circuit consisting of R2 and R3? 90 ohms 20 ohms 10 ohms 45 ohms Objects that allow electrical current to flow are called ______. nonconductors conductors batteries circuits When placed into a circuit, how are electronic components usually connected? positive terminal to positive terminal in parallel as a combination of series and parallel in series in series in series If the length of the filament of a heater is reduced by 10 % , the power of the heater will increase by about 9% increases by 11% increase by about 19% decrease by about 10% An energy source will upply a constant current into the load if its internal resistance is very large as compared to the load resistance equal to the esistance of he load non - e of but less than tha resistance of the load ze o Do you really want to submit this quiz?
