Để trở thành một thợ điện giỏi như những người thợ điện chuyên mắc điện cho
từng hộ gia đình thì hôm nay chúng ta rèn kĩ năng của người lao động trong
ngành điện và tìm hiều quy tắc mắc ampe kế, vôn kế, sau đó mắc mạch điện đơn
giản rồi tính toán các đại lượng.

Một trong những tinh thần vượt khó
khăn của nhà bác học người Pháp
André Marie Ampère đã để lại cho
thế hệ sau biết thêm về dụng cụ đo
cường dòng điện không chỉ là
ampeke mà còn có đồng hồ đa năng
với nhiều chức năng, có loại dùng
kim chỉ có loại dùng số.
Những người làm nghề sản xuất các
thiết bị điện đã dựa vào đó để chế
tạo ra đồng hồ đa năng loại đơn
giản nhất có thể đo được I, U, R có
các thang đo và giới hạn đo khác
nhau phù hợp với nhu cầu của
người sử dụng.

Một trong những tinh thần vượt khó
khăn để nghiên cứu khoa học của
nhà bác học G.S.Ôm đã để lại cho
chúng ta kho kiến thức quý giá để
loi theo nhà toán học của chúng ta
là GS Ngô Bảo Châu cũng có được
thành tựu của mình. Đối với chúng
ta để làm được điều này thì cần phải
chăm chỉ hơn nữa.

Hệ thống đường dây tải điện 500kV
của nước ta dài 1530km, gồm ba
đường dây tải mỗi đường dây tải
này có 4 dây liên kết lại bằng các
khung kim loại. Cứ 1 km của mỗi
dây có điện trở 0.085 ôm thì có thể
tính được điện trở của một dây này
là 130 ôm mà điện trở của dây tỉ lệ
thuận với chiều dài của dây. Nếu em
nào học và làm nghề điện lực sau
này kéo đường dây thì cần phải biết
điều này.
