Parallel circuit Definition and 108 Threads

I have a question about series and parallel circuits We made a simple series circuit using three light bulbs when we measured the current with the ammeter at each end of the light bulb, they were 30mA at the source, then it began to change to 40,40,60,60,1.6, and 2.3 Do you think this result...

I have a circuit with a capacitor, resistor, and inductor all in parallel with each other. I have to write the differential equation governing the voltage. However, when I attempt to do that [using Kirchoff's Voltage Rule] I will end up with: Vc + Vl = 0 and Vl + Vr = 0 However, this implies...

I know this might sound simple to you but I was just wondering is the bumper car grid a series or parallel circuit? I need the answer for a project that I'm working on so that's why :smile:

Q: Two bulbs x and y are connected in parallel to a new dry cell. The switch is closed. If bulb x is unscrewed, the brightness of bulb y will a) double b) halve c) remain the same d) become 0 A: a? The current from the first branch would go into the second branch?

What's the difference between a short circuit and a parallel circuit? In a short circuit, my teacher told me that no current will passs through the more resistive path. I doubt it. If this is wrong, then I could distinguish the difference and similarities between them. If not, I really need...

My science teacher gave me this formula for resistance in parallel circuit. \frac{1}{R_{eq}}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+... Thats exactly how he wrote it. I would like this using the summation sigma \frac{1}{R_{eq}}=\sum_{R=\frac{1}{R_n}}^n Is that right? I am sure it's...

A capacitor is connected in parallel with a RL branch and a source providing a frequency omega=(LC)^(-1/2). What is the power factor, knowing that R=1000 Ohm, omega 2000 rad/s and L=1H? Its not difficult to find C=0,25 microC and XL=2000 Ohm XC=2000 Ohm but what to do next? How can I...

I have a problem that I'm working on, not sure what equation to use for this: The current in a 54 ohm resistor is 0.13 A. This resistor is in series with a 23 ohm resistor, and the series combination is connected across a battery. What is the battery voltage?
