Resistors having resistance of 15 W,
20 W and 10 W are connected in parallel.What is the effective resistance in the circuit?
Pratishtha2003:
the si unit of resistance is ohm not watt
first confirm the given values are power or resistance?

the effective resistance in parallel is as follows:
1/R=1/R1+1/R2+1/R3
1/R=1/15+1/20+1/10
1/R=13/60
Therefore,R/1=60/13
R/1=4.61..
Thank you.
