The Toroid is form when you have wound conductor around circular body. In this case you have magnatic field inside the core but you dont have any poles because circular body dont have ends. This can be used where you want minimum flux leakage and dont need magnatic poles. i.e. toroidal inductor, toroidal transformer.
The Solenoid is forn when you wound conductor around body with limb. In this case magnatic field creates two poles N and S. Solenoids have little bit flux leakage. This used where you want magnatic poles and flux leakage is not an issue. i.e. relay, motors, electromagnates.
1 == toroid
2= solenoid
B. Energy can change from one form to another
Answer:
Total Resistance in circuit is Fourteen Ohms <u>(14 Ω).</u>
<u></u>
Explanation:
How do we know, if the resistors are connected in series, the total resistance is the <u>sum of all the resistors.</u>
(Important: The total resistance can only be added just when the resistors are <u>connected in series</u>)
Then, total resistance (<em>TR </em>) is the sum of all resistors (<em>T1 + T2</em>, in this case)
TR = T1 + T2
According to problem data, we have:
TR = 8 Ω + 6 Ω
TR = 14 Ω
