Question

You are given the following current- time graphs from two different sources:

Now, answer the following questions:

Name the type of current in two cases.
Identify any one source for each type of these currents.
What is the frequency of current in case (b) in India?

Use above graphs to write two differences between the current in two cases.

✓

Answer

In graph (a) current is constant and in graph (b) current is different.

Source of (a) is battery and source of (b) is AC generator.
50Hz frequency of current in case b.

Alternating current		Direct current
1.	Both the magnitude and direction of current varies within equal intervals of time.	Direction of current does not vary with time and remains constant.
2.	The frequency of ac is 50Hz or 60Hz depending upon the country.	The frequency for direct current is zero.

Read the following and answer any three questions from (i) to (iv).The electrical energy consumed by an electrical appliance is given by the product of its power rating and the time for which it is used. The SI unit of electrical energy is Joule. Actually, Joule represents a very small quantity of energy, and therefore it is inconvenient to use where a large quantity of energy is involved. So for commercial purposes we use a bigger unit of electrical energy which is called kilowatt-hour. 1 kilowatt-hour is equal to $3.6 × 10^6$ joules of electrical energy.

The energy dissipated by the heater is E. When the time of operating the heater is doubled, the energy dissipated will?
The power of a lamp is 60W. The energy consumed in 1 minute will?
The electrical refrigerator rated 400W operates 8 hours a day. The cost of electrical energy is ₹ 5 per kWh. Find the cost of running the refrigerator for one day?
OR

Read the following and answer any three questions from (i) to (iv).All the elements on the left side and in the middle of the periodic table (except hydrogen) are metallic elements or metals. Also, majority of elements in periodic table are metals. ln the modern periodic table, the metals are separated from non-metals by a zig-zag line. Some non-metals are gases, some are liquids and rest are solids at room temperature. They generally differ from metals in appearance and in other physical properties. Some elements, that lie along the zig-zag line that separates metals from non-metals, have properties that fall between those of metals and non-metals. These elements are regarded as semi-metals or metalloids.
