Well, in ohms law (electricity basics) P=I2 x R (the '2' is meant to be the squared symbol)
P is Power in Watts
I is current in Amperes
R is the resistance of the circuit in Ohms
So Power = the current squared, multiplied by the resistance.
L is sometimes used as a symbol for inductance, so the 'L' could mean the power dissipated by an inductor.
If this is a riddle then I don't see the funny side, but I could be missing the point!

How can you solve for resistance when given power?
Depends on the voltage. R equals V2/P . Or the current: R equals P/I2 .
What does I x V equals R stands for?
Nothing. If I is current, V is voltage, and R is resistance, then V=I*R and V*I=P, where P is power.
What is the Amperes difference between a 2 light bulb series circuit and 2 light bulb parallel circuit?
if the bulbs are identical, we can assume that both of them have the same resistance R. in series : the flowing current is I1, the voltage at the ends of the 1st Bulb is V1 and the voltage at the ends of the 2nd bulb is V2. V1 = V2 = V since they have the same resistance and V is the voltage applied on the ends of the whole circuit. the Total circuit resistance is 2*R. thus : I1 = V / 2*R => V = 2 * I1 * R (1) in Parallel mode : the current flowing in the first bulb is i1 and the current flowing in the second bulb is i2. i1 = i2 since R1 = R2. I2 = i1 + i2 i1 = V / R and i2 = V / R => I2 = (V /R ) + (V / R) = 2*V / R => V = I2 * R / 2 (2) (1) and (2) => 2 * I1 * R = I2 * R /2 => I1 = I2 * R / (R * 2) => I1 = I2 / 2 above, is the mathematical solution of the problem, but the result is directly predictable since both bulbs are identical. in summary the current that flows in the circuit when wired in series is half of the current when wired in parallel. also note, that the voltage in series on the ends of each bulb is half of the voltage when wired in parallel.
What is r equals r equals r?
the answer is r.
What is the abbreviation for pqrrrr?
P stands for Preview Q stands for question ,r stands for reading .r stands for recite ,r stands for reflect and r stands for review which are the essential steps of good studying.
Why do you represent current as 'i' even though its unit is ampere?
I is just a sign assigned to represent current in equations and ampere stands for its unit of measurement. So I equals V divided by R where I stands for current, V stands for voltage, and R stands for resistance. And thats just as representation all 3 representations have their own measurement units: For I its Ampere, for V its Volts and for R its ohm's.
What does R stands for in WagonR?
I Guess that R stands for Recreation
How do you put this into a formula needs times faith equals motivation plus action equals results?
it can be written as follows nf=m+a=R Where n stands for needs, f for faith,m for motivation, a for action and R represents result.
What has the author Charles R Bauer written?

How many amps are in a circuit with 125 milliwatts and 47 ohms?
You have two known values: P and R. Recall the formula for Power: Power (watts) = I2 R Basic algebra will help convert the power equation to solve for current: Step 1: P/R=I2 Step 2: SQRT(P/R)=I
What does pv equals nRt equals NkBT stand for?
P stands for pressure. V stands for volume. n stands for the number of moles of gas. T stands for temperature. R is a little tricky, you could change the formula by using different units, R changes in value depending on what units you use in order to balance the equation. If you use Kelvin, Liters, Moles, and atmospheres then there is a specific number for R which you need to use and can be looked up.
If r equals 5z then 15z equals 3y then r equals?
if r=5z and 15z =3 then r=10y
