Question

(1). Three equal resistors connected in series across a source of e.m.f together dissipate 10w of power .what should be the power dissipated if the resistor are connected in parallel across the same e.m.f? (2) if electrons are caused to fall through a PD of 10 index 5 volt determine their final speed if they were initially at rest. (3) two electrons are 1m apart .show that the fore between them is 2.30410 index -5 Newton
