Question

1.Three resistors R1 ,R2,R3 are connected in series iftheir resistances are 50hm,30hm and 20hm respectively.Assuming R is their total resistance what is the value of R?
a.if the resistors mentioned above are now connected in parallel, what will be the combined resistance 2. Two cells each of voltage e.m.f. 1.5volts are connected in series, what is their total output voltage
b. What will be the resultant voltage if you now connect them in parallel

Answer 1

two cell os current and you can be charged
