Calculate the total resistance of each combination a. 3 fourth ohm resistors in series

b. a 5 ohm and a 2 ohm resistor in series

c. 2 fourth ohm resistors in parallel

d. a 6 ohm and 12 ohm resistor in parallel

ALL 4 NEED AN ANSWER

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

i don't understand. explain it clearly

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
