In this skill sheet you will review the relationship between electrical power and Ohm’s law. As you work through the problems, you will practice calculating the power used by common appliances in your home.
The amount of water in the tank is defined as 1 volt and the "narrowness" (resistance to flow) of the hose is defined as 1 ohm. Using Ohms Law, this gives us a flow (current) of 1 amp. Using this analogy, let's now look at the tank with the narrow hose. Because the hose is narrower, its resistance to flow is higher.
3 paź 2024 · Calculation Formula. To calculate resistance (R) in ohms using power (P) in watts and voltage (V) in volts, the formula is derived from Ohm's Law and the power equation: \ [ R = \frac {V^2} {P} \] Where: \ ( R \) is the resistance in ohms (\ (\Omega\))
OHM'S LAW WORKSHEET USEFUL EQUATIONS: Current(I) (in amps) = Voltage (V) (in volts) I = V or V=I x R Resistance(R) (in ohms) R Power(Watts) = Voltage(volts) X Current(amperes) 1. What current flows through a hair dryer plugged into a 110 Volt circuit if it has a resistance of 25 ohms? 2.
