Analog meter.Three disadvantages compered to the Digital meter
A digital meter has a finite number of digits it can display
A digital meter is usually better because its resistance is much higher
Digital multimeters can solve most electrical problems - at the hands of a qualified electrical test profession. In fact, With a good wiring diagram and a good meter, a trained electrical professional can find the cause of almost any problem.
You can drop a digital meter.
Didital meter. Three disadvantages compered to the Analog meter
Analog has an infinite number of positions it can lay on the scale.
Switched range analog multimeters are very cheap but are difficult for beginners to read accurately, especially on resistance scales.
Analog multimeters can be used to find electronic and electrical short circuit problems.

Asbestos
Asbestos where can you find it ??
You can find it in old houses made in the 1930-1950s
You can find it in Artificial ashes
You can find it in oil and coal furnaces
You can find it in hot water pipes and steam pipes in older houses.

What i have learnt past week.
have learnt about fires and how to put them out in health and safety also how to find an angle with a triangle also how to find an unkown side.
pythogoras theorem
To find out what C is you must use a simple equation which is A2+B2=C2
If A is 25 and b is 46 it would be 25squared+46squared=2741
Then you would spuare root 2741=52.35
C= 52.35
If A is 25 and b is 46 it would be 25squared+46squared=2741
Then you would spuare root 2741=52.35
C= 52.35
steps to solving unknown angle
label your triangle
estimate your answer
To find angle b first figure out what fuction you want to use in this case SIN
Now insert known dimensions (use inverse sin) sin 10 divided by 19= 37.75degrees.

dangerous ladder.
This is a very dangerous situation. This ladder will be very unstable and at any time and point could just collapse.

Hazard Identification
Hazard identification is spotting or finding a hazard and either Eliminating, Minimising or Isolating that hazard.

Ohms law
ohms law
the current in a cicuit is proportional to voltage and inversonly proportional to resistance
this means when the resistance is high the voltage is low and when the voltage is high the resistance is low.
