Aug 02, 2015 · I use symbol (b). In two cases nodal analysis can be done with voltage sources. Case 1: If the voltage source (dependent or independent) is connected between two non-reference nodes, the two non-reference nodes form a generalized node or supernode, we apply both KCL and KVL to determine the node voltages.
Mar 11, 2011 · (b) DISTANCE per minute = RADIUS x 2 x π x RPM. We already know (c) POWER = FORCE x DISTANCE per minute. So if we plug the equivalent for FORCE from equation (a) and distance per minute from equation (b) into equation (c), we get: POWER = (TORQUE ÷ RADIUS) x (RPM x RADIUS x 2 x π) Dividing both sides by 33,000 to find HP,
It's a little shabby, but hopefully the color helps you identify or differentiate between them. And now that I know the voltage, again apply Ohm's law, this time to calculate the current. So that's the whole game over here. If you know voltage, you calculate the current. If you know the current, you calculate the voltage.
Feb 08, 2015 · The voltage across (or is it between ?) the terminals is the same (why ?) as the voltage drop at the branch with the 2, 12 and 10 Ohm resistors, which is 45 Volts. This was found by first finding the current flowing through the branch with the current division principle, i = 3.75 A.
The corresponding quantities are now given by Q, V, E and U are related to previous quantities as (a) Q> Q0 (b) V> V0 (c) E> E0 (d) U> U0 02--- A parallel plate air capacitor with no dielectric between the plates is connected to the constant voltage source.
The ratio between the number of actual turns of wire in each coil is the key in determining the type of transformer and what the output voltage will be. The ratio between output voltage and input voltage is the same as the ratio of the number of turns between the two windings.
A generator voltage regulator is needed to maintain a constant voltage within an AC or DC generator. While functioning, the engine within a generator works at different speeds according to the output that needs to be produced. An over-worked engine could heat up and produce surges that can be detrimental to the generator.
