What is the current in a parallel circuit which has two resistors (17.2 ohms and 22.4 ohms) and a power source of 6.0 volts?

Answer : The current in a parallel circuit is, 0.6 A

Solution : Given,

Resistance, = 17.2 ohm

Resistance, = 22.4 ohm

Voltage = 6.0 V

First we have to calculate the total resistance in a circuit.

Now put all the given values in this expression, we get the total resistance in a circuit.

Now we have to calculate the current flowing in a parallel circuit.

Using ohm's law :

where,

V = voltage

R = resistance

I = current

Now put all the given values in this formula, we get

Therefore, the current in a parallel circuit is, 0.6 A

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
