A 9.8Ω resistor and a 4.6Ω resistor are connected in parallel with a battery. The current across the 9.8Ω resistor is measured as 0.25 A. Find the potential difference across the battery. ___ Volts

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

i think the answer would be reserve.

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
