A 12 - V battery is connected across a device with variable resistance.As the resistance of the device increases, determinewhether the following quantities increase, decrease, or remainunchanged. Indicate your answers with I, D, or U, respectively.(a) The current through the device. (b) The voltage acrossthe device. (c) The power consumed by the device.
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
A 12 - V battery is connected across a device with variable resistance.
As the resistance of the device increases, determine
whether the following quantities increase, decrease, or remain
unchanged. Indicate your answers with I, D, or U, respectively.
(a) The current through the device. (b) The voltage across
the device. (c) The power consumed by the device.
