Answer:
−1.9 × 10−5 Wb
Explanation:
Magnetic flux is the product of average magnetic field times the perpendicular area that is crosses times the angle between planar area and magnetic flux
Finding the area
Area = πr² = 3.14*0.075*0.075
Area=0.01767 m²
Magnetic flux = 0.01767*0.00110*cos 0
Magnetic flux =0.000019 = −1.9 × 10−5 Wb
Answer:
14.57 ohms
Explanation:
Here in the figure ,Rb & R₄are in series & also Rc & R₅ are in series. As they are in series , ( Rb + R₄ ) & (Rc & R₅) are in parallel . So the equivalent resistance in that branch = ( 2 + 18 ) ║ ( 3 + 12 )
= 20 ║ 15
= (20×15) / (20 + 15)
= 8.57 ohms
Also Ra ( 6 ohm ) is in series with that branch ,. So the equivalent resistance of the whole circuit = 8.57 + 6 = 14.57 ohms.
