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!
You can solve for resistance using the formula ( R = \frac{V^2}{P} ), where R is the resistance, V is the voltage, and P is the power. By rearranging the formula, you can solve for resistance by dividing the square of the voltage by the power.
Nothing. If I is current, V is voltage, and R is resistance, then V=I*R and V*I=P, where P is power.
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.
the answer is r.
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.
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.
I Guess that R stands for Recreation
Charles R Bauer has written: 'Basic PL/I programming' -- subject(s): PL/I (Computer program language), Programming, IBM 360 (Computer)
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.
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
if r=5z and 15z =3 then r=10y
It would appear that r = y
