If the bulb is in series with something else, then . . .
-- The brightness of the bulb depends on the <em>other</em> device in the circuit.
-- If the other device is designed to use <em>less power</em> than the bulb, then the
other device gets <em>more power</em> than the bulb gets.
-- If the other device is designed to use <em>more power </em>than the bulb, then the
other device gets <em>less power</em> than the bulb gets.
-- If the other device is removed from the circuit, then the bulb doesn't light at all.
This description of the often-screwy behavior of a series circuit may partly explain
why the electric service in your home is not a series circuit.
Solution :
The relationship between the strength of magnetic field and the radiusof a charged particle's path is obtained through Newton's second law, which is given by :
F = ma
F = qvB and 
Substituting these values in the second law of Newton,

Now solving for B, we get:


= 0.261 T
The field strength can be obtained by using the technology of today.
The Mantle lies underneath the crust.
Answer:
1 km
Explanation:
= Gap between antennas = 600 m
= Frequency = 1 MHz
= Distance to receiver = 2 km
c = Speed of light =
