A small light bulb is connected to a 20 V battery and draws 1.25 A of current. What is the net resistance of the bulb? *

The net resistance of the bulb : 16 Ω

Electric current (symbolized by the letter "i) is the amount of charge flowing in the conductor of each unit of time  

Can be formulated:  

Q = charge (Coulomb)  

t = time (seconds)  

The international standard unit of electric current is Coulomb/second or Ampere (A).  

Electric current is also a ratio between the voltage and the amount of resistance at the conductor.  

Can be formulated  

V = Voltage (volts)  

R = resistance (ohms)  

This formula is also known as Ohm's Law

A small light bulb is connected to a 20 V battery and draws 1.25 A of current, so,

the resistance :

c.
