Answer:
(a): When the four resistors are connected in series the equivalent resistor value is Req= 48Ω
(b): when the four resistors are connected in parallel the equivalent resistor value is Req=3Ω
Explanation:
R=R1=R2=R3=R4= 12Ω
(a)
Req= R1+R2+R3+R4
Req= 48 Ω
(b)
Req= (1/12 * 4)⁻¹
Req= 3 Ω
Answer:
344.8 x10^-8J/m³
Explanation:
Using=> energy intensity/ speed oflight
= 1000/2.9x10^8
= 344.8 x10^-8J/m³
