Ohm's Law explains the relationship of which electrical quantities?

The headlights of a typical car are powered by a  12.0 V battery. What is the resistance of the headlights if they draw  3A of current when turned on?

Which is true?

What do you call the device that is used for storing the electric charge?

Which is true?

A typical household lightbulb requires  of 0.50 A current. If this light bulb is turned on for one hour, how many coulombs of charge pass through the light bulb?

What is a dielectric?

If $$R=\frac{\rho L}{A}$$  and the cross sectional area of the wire is $$A=\pi r^2$$   Calculate the electrical resistance of the fluid filled rubber-tube displacement transducer that is  0.75 m long with a radius of 0.3 m . The resistivity of the fluid is 0.80 ohm-m.

Who is considered as the Isaac Newton of electrodynamics?

A long wire is connected to the terminals of a battery. In eight seconds,  9.6 x 10^20 electrons pass across the wire. If q=ne and I=q/t, how much current is generated?

The potential difference across terminals with no current flowing.

emf = TV + Ir. Since TV = IR, emf is also equal to $$\ I\left(R+r\right)$$  

What is the emf of the cell whose internal resistance is 0.15 ohms and delivers a 0.50 A to resistane of 2.85 ohms?

This is the working voltage of the battery.

Which of the following refers to the flow of positive charges per unit time?

If I = q/t and N=q/e, how many electrons move through a flashlight for two hours of use? Assume that a normal flashlight uses  0.1 A of current.

What will happen if a negatively particle is placed between two parallel conducting plates with positively charged upper plate and negatively charged bottom plate?

If the resistor has a constant resistance and obeys ohm’s law, it's resistance is called:

What is the resistance of a copper wire with cross-sectional area of  0.501 cm^2 and length 2m of  if the copper has a resistivity of 1.68 x 10 ^-3 ohms ?

What would be the electric potential energy of the negatively charged particle if a negatively particle is placed between two parallel conducting plates with positively charged upper plate and negatively charged bottom plate?

What type of current flow is shown in the picture?
