1. A 20-volt relay has a coil resistance of 200 ohms. How much current does it draw? 2. A series circuit has 1200-ohms of total resistance with 12 V as the power supply.
What is the total current of this circuit?\
3. A transformer is connected to 120 volts. Find the current if the resistance is 480-ohms?
4. If a small appliance is rated at a current of 10 amps and a voltage of 120 volts, the power
rating would be Watts. (P = I V )
5. Find the applied voltage of a telephone circuit that draws 0.017amperes through a resistance of 15,000 ohms.

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

scientific laws are the result of testing theories and proving them to be facts.
