c is what you want from a fire ?
I think it is B Because it sounds like the best choice
Answer:
Solar energy, Wind energy, Hydro energy, Tidal energy, Geothermal energy, Biomass Energy.
Explanation:
I hope that it helps you...
Answer:
a) 588.235 ohm ( all the 3 resistors are in parallel )
b) 10 A
c) Current flowing -
in 20 ohm resistor = 6.25 A
in 100 ohm resistor = 1.25 A
in 50 ohm resistor = 2.5 A
d) Voltage drop across all the resistor = 125 V
(As all the resistors are in parallel all the resistors will have the same voltage drop )
e) Power dissipated -
in 20 ohm resistor = 781.25 W
in 100 ohm resistor = 156.25 W
in 50 ohm resistor = 312.5 W
(Power = Current × Potential Difference)
