E stands for voltage in this case.
E=MC squared was Einstein's formula for splitting the atom. Energy = mass X speed of light squared
m is mass in the equation.
E is energy.
In the formula E=CM2, C = the speed of light.
R = E/I = 110/4.75 = 23.16 ohms (rounded)
Ohms law. R = E/I,where R= resistance in ohms, E = voltage in volts, and I = current in amperes.
I=e/r
The "E" stands for "Electromotive Force", also known as Voltage.
If: E*I = P Then: I = P/E
Assuming this is a DC circuit, use Ohm's Law to find the answer. Ohm's Law states E = I x R (Voltage = Current x Resistance) E = 0.5a x 110 ohms E = 55 volts A/C requires a more complicated formula and more information in the given question.
........V I = ------ ........R I = Ohm's Law V = Voltage R = Resistance (Ignore the dots they stop V and R from moving to the left!)
The formula you are looking for is R = E/I
Ohms law: E (Volts) = I (Amps) X R (Ohms) Do the math!
Ohms law equations are I = W/E, I = E/R and I = Sq Root of W/R.
The formula you are looking for is I = W/E.
Ohms law states E=I*R. Isolating I we get, I = E/R.I = 60V/12ohms = 5 amps.
Light Emitting Diodes (LED) solid state devices are current dependant. LED have ratings for the max current allowed to the LED device. A typical current allowed to a LED is 20ma. Ohms Law is used to determine the resistance required to limit the current to your desired current. The formula is used in this manner: E=12VOLTS the desired current is I = 20ma. R = E/I = 600 ohms. Where E=2 volts dc and I=20ma R= E/I = 100 Ohms.
