Power P0 = I0 ∆V0 is delivered to a resistor of resistance R0.If the resistance is doubled (Rnew = 2R0) while the voltageis adjusted such that the current is constant, what are theratios (a) Pnew /P0 and (b) ∆Vnew /∆V0? If, instead, the resistanceis held constant while Pnew = 2P0, what are the ratios(c) ∆Vnew /∆V0 , and (d) Inew /I0 ?
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.
Power P0 = I0 ∆V0 is delivered to a resistor of resistance R0.
If the resistance is doubled (Rnew = 2R0) while the voltage
is adjusted such that the current is constant, what are the
ratios (a) Pnew /P0 and (b) ∆Vnew /∆V0? If, instead, the resistance
is held constant while Pnew = 2P0, what are the ratios
(c) ∆Vnew /∆V0 , and (d) Inew /I0 ?
