A strong lightning bolt transfers about 24 C to Earth. How many electrons are transferred? The elementary charge is 1.60218 × 10−19 C.

Number of electrons transferred in the lightning bolt, n = 1.498 × 10²⁰ electrons

Explanation:

Total charge transferred by lightning bolt, Q = number of electrons transferred by the lightning bolt, n × charge on one electron, q

Q = 24C

n = ?

q = 1.60218 × 10⁻¹⁹C

n = Q/q = 24/(1.60218 × 10⁻¹⁹) = 1.498 × 10²⁰ electrons

b) phosphorus pentoxide

the higher the current the higher the mag field around it the higher the influence on the compass
