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 your motto in math?
One, two, square root of three. M V R equals N H-bar. Rah ! E to the X, D U, D X. Rah ! The NOT of the ORs is the AND of the NOTs. P V equals N R T. The NOT of the ANDs is the OR of the NOTs.
What is the voltage of a battery if it is connected across an 8 ohm resistor and 0.75 amps of current flows through the resistor?
The battery has 6 volts across its terminals. The way to discover it is to apply Ohm's law. It (Ohm's law) comes in 3 "flavors" that look a bit different but all say exactly the same thing. Here they are: E = I x R [Voltage equals current times resistance.] I = E/R [Current equals voltage divided by resistance.] R = E/I [Resistance equals voltage divided by current.] In these equations, voltage is E, current is I and resistance is R. They are measured in units of volts, amperes (or amps) and ohms, respectively. In your problem, we have the resistance (R) and the current (I). We need to find the voltage (E), and the formula E = I x R is the logical choice to discover the voltage. As E = I x R here, E = 0.75 x 8 = 3/4 x 8 = 6 volts. Piece of cake.
How can you calculate the current in 40 X 40W tube lights in 230V?
power is = V2/R so 40x40= (230)2/R R= 33.25 now V= IR where I is current 230= IXR I= 230/33.25 = 6.9 amp
What times what equals equals 76?
19 x 4
What times what equals 6 times equals 729?
2 x 3 = 6 x 121.5 = 729
How do you solve x divided by r equals v for x?
x/r=v x=vr
What does the you stand for P equals V x I?
There is no "you" in P = V x I
How do you calculate the resistance in a circuit in which a 9-volt battery produces 3 amperes?
Where V=stands for voltage, I=stands for current and R=stands for resistance. voltage=current multiplied by resistance so, by transposition, resistance=voltage divided by current. or R=V/I, R=9/3 The resistance is 3 ohms.as by ohm's law, v=irr = v/itherefore the resistance is 9/3=3 ohms

What is the power dissipated by a 9 ohm resistor with 3 amps flowing through it?
Here are a few easy and related equations. V = Voltage, I = Current (amps) R = Resistance, (Ohms) V = I X R R= V / I I = V / R Power = Watts = W, is expressed as V X I. Since V =I X R, W then also = R X I X I Which is I **2 X R Same as V**2 / R So, if your I = 3 and your R = 3, and because I X R = V, 3 X 3 =9 Volts (Note: capacitance and inductance can also influence the amount of current flow in a system. This resistance is referred to as reactance. Both reactances are a function of the frequency of the Voltage applied.) Have a wonderful day. Bob
What is the ohm's triangle?
V/IXR This helps you to remember the three versions of Ohm's Law: V = I X R R = V/I I = V/R
How do you figure resistive amps?
You can use the formula known as Ohm's law: V = I x R so the voltage equals the current times the resistance.
Is the formula diameter equals 4 x r correct?
No. Diameter = 2 x r
How do you compute volts?
V = I x R; V = Volts, I = Current in Amps, R = Resistance in Ohms.
What is the meaning of V equals L x W X H?
volume
Does v equals 1 x w x h?
yes 8)
What is V plus x equals Wsquared what is x?
x = W2 - V and you cannot get any further than that since neither W nor V are known.
