Answers & Comments
a. voltage
kasi yun yung nabasa ko
The voltage, power rating (watts), and current are already analyze.
Here is the resistance:
6.85, 7.2, 8.57, 8, 15
How is electric power related to:
A. VOLTAGE
Voltage provides the work required in Joules to move one Coulomb of charge from A to B.
B.CURRENT
Current is the rate of movement (or rate of flow) of the charge. This is because electrical power can also equal voltage times amperes, that is: P = V*I.
C.RESISTANCE
The power dissipated in a resistor is given by P = V2/R which means power decreases if resistance increases. Yet this power is also given by P = I2R, which means power increases if resistance increases.
Hope it's help
