Ohm's law relates the current, voltage, and resistance in a circuit. Use Ohm's law to determine what will happen to the remainin

g variable if one is held constant and another is changed. Assume that, originally, the resistance is R 0 , the current is I 0 , and the voltage is V 0 .

Answer:

Ohm's Law states that current through any conductor is directly proportional to the potential difference across the ends of the conductor.

Explanation:

Ohm's Law states that current through any conductor is directly proportional to the potential difference across the ends of the conductor.

<u>Mathematically:</u>

I\propto V

I_0=\frac{V_0}{R_0}

where

R = resistance of the conductor

i.e.

  • When resistance is held constant the current is directly proportional to the voltage.

Other form of the equation is:

V_0=R_0.I_0

  • For a constant current the voltage is directly proportional to the resistance of the conductor.

V_0\propto R_0

  • For constant voltage the current is inversely proportional to the resistance of the conductor.

I_0\propto \frac{1}{R_0}

Answer:

Explanation:

According to the Ohm's law, when the temperature of a conductor remains constant, the current flowing through the conductor is directly proportional to the potential difference applied across the conductor.

V = I R

where, I is the current and R be the resistance of the conductor.

When the resistance remains constant, if we increase the potential difference across the conductor, the current also increases.

A bicyclist is initially traveling at 3 m/s. The bicyclist accelerates at 1 m/s2 for 5 seconds.
leonid [27]
The change in velocity is 5m/s which added to the initial 3m/s makes the final velocity 8m/s

Distance = (3*5) + (1/2*1*5^2)= 15+12.5= 27.5m
