Two resistors of 400 Ohm and 600 Ohm are in parallel What is the equivalent resistance?
Use the general equation for resistance in parallel: 1/R = 1/R1 + 1/R2
What is the value of R in ohm in the circuit diagram If the ammeter reads 320mA and the voltmeter 0.84V?
The equation you are looking for is R = E/I. The question wants to see if you know how to convert mA to amps. Do the conversion and then use the equation and you will have your answer.
What is the relationship between current and resistance?
They are proportional to each other with a constant of 1/V, by rearrangment of the formula V = IR.
According to ohm's law resistance is equal to voltage divided by?
The equation you are looking for, R = E/I, is derived from the definition of the ohm, not from Ohm's Law. Ohm's Law is properly-called 'Ohm's Law of Constant Proportionality', which states that, for certain (linear) loads, the ratio of voltage to current is constant for changes in voltage. The above equation applies whether Ohm's Law does or does not.
If a 1 ohm resistor is parallel with a 100 ohm resister what's the total resistance?
If two 1-ohm resistors are connected in parallel, their resistance is 0.5 ohms. If they are connected in series, their resistance is 2 ohms. It is not possible to connect only two resistors in series parallel.

What is the resistance of a parallel circuit with resistances of 2 ohm's 4 ohm's 6 ohm's and 10 ohm's?
R = 1/[1/2 + 1/4 + 1/6 + 1/10] Add up the reciprocals of the resistances, and take the reciprocal of the answer.
What is r times 1 equals 1?
It is a linear equation in one variable r. The solution to the equation is r = 1.
What is the value of R in ohm in the circuit diagram If the ammeter reads 320mA and the voltmeter 0.84V?
The equation you are looking for is R = E/I. The question wants to see if you know how to convert mA to amps. Do the conversion and then use the equation and you will have your answer.
What is the total resistance for 2.2 ohm 1.5 ohm 3.8 ohm 4.5 ohm?
If the loads are wired in series, add the three values to get the total R. If they are in parallel then the formula is 1/R = 1/R1 + 1/R2 + 1/R3 The total resistane when resistors are in parallel is ALWAYS LESS than the lowest individual value.
what resistance is the center of your ohm scale, R x 1?
50

What is ohm's law and write three forms of ohm's law in a equation?
Ohm's law relates voltage, current, and resistance. Voltage is current times resistance Current is voltage divided by resistance Resistance is voltage divided by current
What is the formula for the impedence?
Z = SQR (R² + XL²)Where:Z = Impedance (ohm)R = Resistance (ohm)XL= Inductance Reactance (ohm)
