Answer :
5ohms is the resistance of the brake light in ohms.
What are opposition and an example?
Resistance is the degree to which a substance obstructs or opposes an electric current. Electric current is the flow of electrons. To better understand resistance, imagine how difficult it would be for a person to move from one shop to another in a crowded market.
Resistance and formula are what?
The following is the equation to use Ohm's Law to compute resistance: R = V I, where R is the resistor's resistance expressed in ohms () and V is the voltage drop expressed in volts.
POWER(watts) = VOLTAGE * AMPERAGE
AMPERAGE = POWER(watts) / VOLTAGE
AMPERAGE = 30/12 = 2.5
RESISTANCE(ohms) = VOLTAGE / AMPERAGE
R = 12/2.5 = 4.8ohms
