First one light bulb is connected to a battery. Then two are connected in series to the same battery. Here's the picture: http://home.comcast.net/~chou55/bulb.gif A) When two are connected, the battery puts out a) less current b) more current c) less voltage d) the same current B)...

i just finished reading the circuit chapter in my book hoping it would answer a few of the questions i had in mind, it helped, but not as much as i had hoped...here are a few questions how quickly is a current established throughout a circuit when the switch is closed? (now i suppose the...

I'm having trouble solving this problem: Three resistors(parallel) across a DC voltage source...If the total current through the circuit is I = 2.0A, what is the currect through the 12ohm resistor? The circuit runs into a junction which splits 3 ways. Along each path there's are resistors...

a) I must determine the current in 8 [ome] resistor? Current in the 4[ome] ? a) I started out using ohms law. E=IR, ok. I took the difference between the Voltages eg.12-9 = 3V then multiply by 11 ohms total resistance. b) Did pretty much the same way except that 4 ohms is where most...
