00:05Numerical number 8 of unit 19 electromagnetic induction is a transformer has 1000 tons in

00:14its primary coil and 200 tons in its secondary coil if the primary voltage is 120 volt calculate

00:25the secondary voltage for a step-down transformer so the most important data is the number of

00:41turns in primary coil are given which are 1000 tons number of turns in secondary coil

00:54are 200 tons and the voltage of primary means vp is 120 volt

01:10हमें secondary के voltages calculate करने हैं means vs is equal to watt

01:18यहां पर जो ट्रांस्फार्मर है वो step-down transformer है as we know that

01:29in a step-down transformer

01:38is this is a primary coil and this is secondary coil so number of turns in primary coil are given

01:49which

01:49are 1000 and number of turns in secondary are given which are 200 tons and voltage in primary is given

02:05which is 120 volt और हमें क्या calculate करना है we have to calculate voltage in secondary यहां पर

02:15step-down transformer है तो secondary के जो voltages होंगे वो 120 से कम आएंगे तो फार सलिशन

02:27our calculation we will use the basic equation of transformer is vs upon vp is equal to ns upon np

02:53multiplied with vp के यहां पर voltage in primary divide कर रहे हैं तो बराबर की दूसरी साइड

03:01multiply करेंगे now by putting the given values number of turns in secondary are 200 and

03:10number of turns in primary are 1000 multiplied with voltage in primary is 120 volt this zero will be

03:21cancelled with this zero and this zero will be cancelled with this zero and this zero will be

03:27cancelled with this zero so यहां पर 2 or 12 multiply कर रहें so voltage so voltage in

03:39secondary coil will be obtained as 2 into 12 it will be 24 volt so this is our final answer

03:47is the voltage

03:49in primary is 120 volt and voltage in secondary is obtained as 24 volts
