A battery of 6v is connected in series with three resistors 2ohm, 4 ohm and 6 ohm. calculate the current passing through each resistor and potential difference across each resistor. ​

How does the space charge width change with forward and reverse bias? also, calculate the space charge width for a reverse bias of 4v on a silicon pn junction at t = 300k and doping concentrations of na = 5x1015cm-3 , nd = 5x 1016 cm-3 .

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

In positive numbers less than 1, the zeros between the decimal point and non zero are significant
